Basically you'll end up with seeing more detail in objects that are moving, less motion blur. While 1/50th of a second will look mostly normal, 1/100th of a second will start to have that Saving Private Ryan and/or other War movie action sequence look. Every little detail is in crisp focus, movement is slightly jittery, etc.

Shutter speed on these cameras roughly translates to shutter angle on film cameras. Lower shutter angle on film cameras gets those stutter effects (which is higher shutter speed on DSLRs), and higher shutter angle (lower shutter speed on DSLRs) would be like the effect you get in Gladiator in the opening segment after the first battle where everything starts blurring out. Unfortunately, these cameras only go down to 1/30th of a second, so you aren't going to get that blur effect.
